HARRY L. KASEB, OF CANTON, OHIO.

FEE 1 v nuxinrnrnr SIGNAL.

Application filed October 28, 1916. V Serial no. 128,279.

To all whom it may concern:

Be it known that I, HARRY L. KAsnR, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Auxiliary Signals, of which the following is a specification.

This invention relates to bell ringing apparatus, and the nature and objects thereof will be readily apparent to those skilled in the art to which it appertains, in the light of the following explanation, of the accompanying drawings, illustrating what I now believe to be the preferred embodiment, or mechanical expression, ofmy invention from among other forms and arrangements within the spirit of the invention and the scope of the appended claim.

However, an object of the invention is to provide an apparatus in connection with a polarized bell of a telephone system, and including a normally open switch in circuit with an auxiliary bell and a source of current and means operable by the clapper of the polarized bell whereby the switch is closed and the auxiliary bell sounded while the vibration of the polarized bell clapper is in no wise retarded.

In addition to the foregoing my invention comprehends improvements in the details of construction and arrangement of parts, to be hereinafter described and particularly pointed out in the appended claim.

In the accompanying drawings in which sinnlar and corresponding parts are desig nated by the same characters of reference, throughout the several views in which they appear- Figure 1, is a diagrammatic view illustrating the wiring of my bell ringing apparatus in connection with a polarized bell of a telephone system,

Fig. 2, is an enlarged plan view showing in detail a bell ringing apparatus constructed after the manner of my invention,

Fig. 3, is a view thereof in side elevation, and

Fig. i, is a view similar to Fig. 2, but showing the apparatus as used in a slightly different position.

With reference to the drawings, 1 indicates an instrument box of a telephone system containing the mechanism of a polarized hell, 2 the gongs, and 3 theclapper disposed for vibration between the gongs. The polarized bell is usually operated by a source of alternating current, supplied in the present instance by a magneto generator iconnected to the bell by suitable wiring. My invention comprises in its essentials a base portion 5 which is adapted to be socured to the outside of the instrument box either above or below the gongs, according to the location ofsaid gongs. A' block of insulation substantially T-shaped is secured centrally upon the base and is formed with a longitudinal portion 6 and a transverse portion 7. A member 8 is provided upon the transverse portion 7 of the insulating block, and is formed with fingers 9 which are resilient, and extend parallel to the portion 6 of the insulating block in spaced relation thereto, and extended slightly beyond the extremity thereof. Flat spring members 10 are secured to opposite sides of the portion 6 of the insulated block, and are provided with offset portions 11 at their terminals for disposition in close relation to the contact members 9. A clip 12 issecured to one of the members 10, and is electrically connected to the binding post 13, the two members 1.0 being electrically connected through the insulation block by means of a securing bolt 1-l. The member 8 grounded in the baseto which a b inding post 15 is secured in electrical connection.

Disposed in parallel relation to the members 9 are levers 16, which are pivoted upon studs 17 secured to the base, and lateral projections 18 are formed at adjacent terminals thereof for engagement with the terminals of the members 9. The opposite extremities are slightly reduced as at 19. A longitudinally extending rod 20 is secured to a block 21 which is pivoted to a stud 22 formed upon the base and disposed between the contact members 11. A transversely extending bar 23 is secured to the rod 20 and disposed for engagement with the terminals 19 of the levers 16. The free end of the rod 20 is further provided with a bifurcated portion 24 adapted to embrace the supporting rod of the bell clapper 3.

The auxiliary bell 25 comprises simply an electromagnet in connection with binding posts 26 and 27,'and a vibrating armature for the magnet having a bell clapper 28 and a gong 29. Binding post 27 may be connected to the binding post 15 of my appathe terminals 9 and 11 at each side of the device are alternately brought into con tact in an obvious manner. Electrical impulses of direct current are thus transmitted from the battery to the binding post 13, to the spring members 10 and contacts 11, to the contacts 9, through the base to the binding post 15, through the conductor 30, to the electro-magnet of the bell 25, and back to the battery. The clapper 28 ot' the bell 25 thereby responding with an impact upon the gong for each connection established between either set of contacts 9 and 11, in the meanwhile the sounding of the gongs 2 by the clapper 3 is in no wise retarded or interfered with.

In Fig. 4 the apparatus is illustrated as disposed above the go-ngs, and under the circumstances it is necessary to transpose the rod 20 by changing its connection from the bar 23 to the block 21. The operation of the apparatus in this position is exactly the same as previously described, and requires no additional comment.

By providing an apparatus of the character described, the signal of a polarized telephone bell may be duplicated in a plurality of auxiliary bells located at widely separated points, thus efl'ecting considerable saving in cost of installation as the auxiliary bells are very simple in their construction and quite inexpensive as compared to an equal number of polarized bells which would be necessary, were it not for the interposi ticn of a device of the character described. l/Vhilel have illustrated my invention with some degree of particularity it is obvious that various ways of constructing thesame will occur to those skilled in the arts, and I therefore reserve the right and privilege of changingthe form of the details and otherwise altering the arrangement of parts without departing from the spirit .of the invention or the scope of the appended claim.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is A bell ringing device comprising a base, a substantial T- shaped insulated block mounted thereon, resilient cont-act strips secured to the transverse portion of the block and disposed parallel to and in spaced relation to the longitudinal. portion of the block, contact strips mounted upon the longitudinal portion of the block and having their terminals disposed in spaced relation to the terminals of the first mentioned strips, levers pivoted upon the base for striking engagement with the contact strips, a rod pivoted to a stud projecting from the base between the contact switches, a transverse bar on the rod for engagement with the levers, the terminal of said rod being bifurcated for engagement with the bell clapper of a polar- .ized bell.

In testimony whereof I aflix my signature in presence of two witnesses.
